Apple on Monday released Mac Wi-Fi Update 1.0 to improve compatibility over networks using the 5GHz spectrum, as well as separate incremental EFI updates for late 2012 iMac and 13-inch MacBook Pro with Retina display models.

Recommended for all late 2012 Macs, the Wi-Fi Update is meant to improve protocol compatibility in the 5GHz band, a problem some users have been seeing with their new machines.

In multiple threads on Apple's Support Communities webpage, owners of recently-released iMacs and Retina MacBook Pros complained their computers were unable to recognize 802.11n networks on the 5GHz band.

The 13-inch MacBook Pro with Retina display and newly-redesigned iMac also received updates on Monday, bringing their respective firmware versions up to v.1.1 and v2.0. Along with the Wi-Fi compatibility support, both downloads bring improvements to sleep performance and Thunderbolt router support, while the MacBook Pro update fixes an HDMI display issue.
